Ultra high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering plastic, which is composed of viscosity-average molecular weight more than 2.5 million with a special type of catalyst. UHMWPE pipe has many properties: very high wear resistance, friction coefficient is extremely small, impact resistance, corrosion resistance, no fouling, excellent resistance to internal pressure strength, resistance to environmental stress cracking resistance, good self lubrication, anti adhesion, unique low temperature resistance, excellent chemical stability. All above makes UHMWPE pipe to be the most valuable wear resistant pipe. UHMWPE pipe can work for a long time in - 269 degrees to 80 degrees, which is widely used in metallurgical and mining mineral processing, power plants, granary, acid and alkali, mining tailing, mud and water coal slurry transportation, terminals, shipyards, oil, natural gas, textile, paper making, food, chemical, mechanical, electrical and other industries.
